Raspberry Pi: 10 Great Add-Ons You've Never Heard Of

Quite possibly the most ambitious accessory designed for the Raspberry Pi SBC is Alex Eames's HDMIPi HD 9-inch portable screen. Alex (blogger for RasPi.TV) has teamed up with Cyntech and Pi logo designer Paul Beech to bring an affordable screen to the Pi platform, for watching movies or to incorporate into a myriad of project designs.

No, the screen is not a full 1080p screen, as the team states -- those are too expensive. However it does have a resolution of 1290x800, which is comparable to the Nexus 7 tablet. Actually, the HDMIPi has a larger surface area, measuring in at 9 inches compared to the Nexus 7's 7 inch screen. The goal was to design a screen that finds the perfect cost-to-size ratio that can compete with the more expensive portable screens currently found on the market.

The team has designed two prototypes that feature the same screen but use different controller boards. The first uses a hand-soldered, 51-wire connection cable, with a stripped-down PCB with all the unnecessary parts removed, such as the VGA chip and adapter. The second is much smaller but still needs to be modified (unnecessary parts removed) as well. The team is currently revising the board again to make it as simple as possible before production begins, which will consist of approximately 1,000 units for both the board and screen.

The project is currently being funded through Kickstarter, and those interested in getting the portable screen can pledge $120 or more, which nets you the screen, the controller board, and a handy case that allows for both the Pi and controller board to be fitted together.

What about out of the box thinking and using an embedded cellphone. The cell has android grade cpu .5 gb ram 2 gb hard disk, wifi, gsm, gps and of course the full suite of android apps.
Here is one I found on amazon

This is the fun part, where the industry is small and everyone is still talking to each other. Soon enough, assuming this industry takes off, we will get to the point where big money is involved and everyone talks through their lawyers and PR departments. It is going to be interesting to see if the open source ethos holds up through this. When IBM published their PC bus specification it was a radical move, and they most likely only got away with doing it because Corporate IBM considered PCs to be inconsequential to "real" computing. This generation is starting out from a different base - I am looking forward to seeing where they end up.
